Title: DV2 DetectionBase knows more about allocation statuses

This PR was spawned from comments in #345. It contains a chunk of refactoring, followed by a few feature adds:

- give a specific error message when an allocation is archived
- notice purged or invalid allocation links and continue seamlessly
- add a bit more instrumentation
